PRINTiNG-PRESS'.

SPECIFICATION forming part of Letters Patent No. 618,490, dated January 31, 1899. Application iiled December 19, 1892. Serial No. 465,614. (No model.)

To @ZZ whom it may concer/t:

Be it known that I, HENRY A. Wrsn WOOD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented anew and useful Improvement in Printing-Presses, of which the following is a specification.

The aim of this invention is to provide a new manipulatingv mechanism for controlling a web of paper or its equivalent. .I have shown the invention as applied as the webmanipulating device for a reciprocating-cylinder web-printing press, and in this application I have further claimed certain improvements in this style of printing-machine.

Figure l is a side elevation of a printingpress embodying my improvements.

Fig. 3 is a sectional elevation illustrating the path of the web. Figs. 4, 5, and 6 are similar diagrams illustrating the operation of the parts; and Figs. 7 and 8 are views similar to Figs. 4 and 6, illustrating a modification of the feeding apparatus.

The principal part of this invention relates to an improved manipulating mechanism for handling a web of paper or its equivalent. This manipulating mechanism is espe. cially applicable to any form'of machine in which a web or its equivalent is to have an intermittent movement in a part ofthe mechanism'. a traveling-cylinder web-press in this case,

to which 'the same is especially'adapted; but

it is to be understood, of course, that the improved manipulating device can be applied to any mechanism in which the same is found useful. without departing from thescope of my invention as expressed in the claims.

I have shown the sameas applied to are secu red in anysuitable manner term-beds A and B, upon which the usual printingforms or type may be placed to make the impression. These form -beds, as shown, are arrangedin different horizontal planes and are parallel, but are not placed in the same vertical plane, or, in other words, one bed is arranged horizontally in advance of the other.

This arrangement of beds ina traveling-cylinder printingpress is notspeciii-cally claimed in this case, as the same is claimed in my companion application vfor patent -led January 3, 1898, Serial No. 665,358.l

Coacting with the bed A is the reciprocating impression-cylinder C, and coacting with the bed B is the reciprocating cylinder D, which cylinders are both mounted in a suit able carriage, as hereinafter described.

E represents the'roll of paper, which may be mounted in any convenient manner in the presslframe orv otherwise and from which the web is led.

F F denote the lform-inking are mounted so as to reciprocate with each impression-cylinder, on eachl side thereof, and which are..adapted to ink the forms in the usual well-known manner. Any of the usual means may be used for supplying ink to these form-inking rollers, and it is not thought necessary to show this inking apparatus in thiscase, as the same is well understood. G represent-s the peculiar feeding device or rotarylooper hereinafter referred to, and H .represents what I call the long point of the same.

Referring to Fig. 3, which is a sectional elevation with the parts in theposition shown in Fig. 1, the path of the web will first be described. Fromthe paper-roll E the web is led into the bite ofthe rollers 26, 2,5, and 24,

rolle'rs, whichl ing with the impressonmylinder D. From the roller or guide 2l the web isy led up under the guide-roller 20 andA then up over the guide-roller 19. The guide-roller 19, if desired, maybe adjustable for the purpose of obtaining register of the web between the two i1npressioncylinders. From the roller or guide 19 the web passes to the roller or guide 18, moving with the impression-cylinder C, vthen under the impression-cylinder C, and up over the guide or roller 17, also moving with the in1pression-cylin der C, to the stationary guide or roller 16. From'the guide or roller 1G the web passes down under the roller or guide 15, up over the rotary looper G, and then down into the bite of the delivery-rollers 14, 13, and 12, which may be continuously driven, as by gearing hereinafter described, to continuously deliver the web from the press. It will be seen that the web between the rollers or guides 15 and 14 frms a loop around the rotary looper G.v The rollers 23 and 15 may have brakes, as 28 and 27 coacting therewith, and these brakes are so arranged as to nip theweb during the act of printing, whereby the pull of the cylinders during the printing operation will not affect the amount of web between the rollers 15 and 23 and the webmanipulating mechanism will not affect the web in the press. Then the cylinders are not in impression, these brakes are released and the web can be pulled forward around the impression -cylinders D and C. All these parts, before described, are so arranged that a sheet will be printed for each movement of the impression-cylinders in either direction, or two'sheets will be printed for each complete forward-andbackward movement of the impression-cylinders.

It is evident, of course, that the web could be led in the opposite direction through the press-that is, in through the rollers 12, 13, and 14 and out through the rollers 24, 25, and .2G-and if this were the case all the necessary change that would have to be made would be to throw the long point of the rotary looper G around one hundred and eighty degrees and to gear the feeding in and out rollers to tu rn oppositelyfrom the way shown, so that the loops would be properly formed to act in connection with the properly-moving feeding-in and feeding-out rollers, and in this case the impression-cylinder D would be the second impression-cylinder and would have to carry the offset mechanism, hereinafter described.

I have described my press as a perfectingpress, although, of course, it is evident that many of my improvements could be applied to a single-cylinder machine, in which the web was only printed upon one side, and in that case it might be considered that the upper bed and cylinder were omitted.

The action of the rotary looper G will be hereinafter described.

The rotary looper G is mounted upon a shaft 29, which is turned twice for each complete forward-andbackward movement of the impressioncylinders.

To prevent offset from ,the first printed side of the web upon the second impressioncylinder C, I mount a .fountain in the ciprocating carriage, whichcarriage carries the impression-cylinders,and so arrange the same that the fountain will deposit a thin coating or film upon the surface of the second impression-cylinder, whereby offset will be pr'cvented. This fountain may be organized as fllows: A plush roller 3l is arranged to bear against the surface of the second impression.-

`cylinder C, and bearing against this plush roller is a metal distributer 32, which hears against the fountain-roller 33, which is arranged in the fountain 34. This fountainroller 33 is arranged so as to nearlycover the entire top of the fountain 34, whereby/thc liquid will be prevented from splashing as the impression-cylinders reciprocate. The impression-cylinders C and D have on the ends or the shafts thereof the usual gears 35, which mesh with stationary racks 36, secured to the sides of the form-beds, as shown in Fig.

2, whereby as the impression-cylinders are reciprocated they will oscillate and always keep in register with the form-beds.

gear 37, mounted on the shaft of the plush roller 31, is driven, and this gearing is pref erably so proportioned that the plush roller 31 and the impression-cylinder C will have the same peripheral speed. On the outside end of the shaft of the plush roller 3l is arranged a small pinion 38, which meshes with and` drives a large gear 3S), fastened on the outside end of the roller 32, and this gearing is proportioned, as show n, so that the distributor 32 will turn at `a much slower pcripheral speed than the plush roller 31,whe'rc by there will be considerable slip between the plush roller and the distributer. sired, the fountain-roller 33 may be geared to turn with the distributer 32 at the same peripheral speed, although this is -not always necessary, as the fountain-roller 33 maybe turned simply by contact with the distributor 32. As the gearing on the side of the cylinder oscillates of course this distributing mechanism will be properlyturned to deposit a thin coating or film on the impression-cylinder C. works substantially on the same principle as that shown, described,and claimed in patent to John H. Stonemetz, granted February 1, 1898, No. 598,122, and the slip between the plush roller and the distributer serves to deposit onlya very thin coating or film upon the impression-cylinder.

The impression-cylinder O is mounted in brackets or blocks 40, which may be tied together, ifdesired, to form a strong framing, and the impression-cylinder D is arranged iu similar brackets 41. These brackets 40 and 41, are bolted or secured to sliding frames or carriages 42, which are gibbed to the guides From the gear 35 of the impression-cylinder C a l'OfI tif,

This offset-preventing device f to operate the machine.

43, formed or fastened on the sidev frames, las

mayhave the usual loose and tight/,pulleys 46 and 47, by which power can be imparted On this shaft 45 is arranged a pinion 48, which meshes with and drives' the large intermediate 49, mounted on a stud 50, secured to the main frame 10, as shown. This intermediate 49 drives'a gear 5l, which is secured upon the end of shaft 52, journaled in the main frame 10, and also on this shaft 52 is arranged a gear 520, which meshes with gears secured upon the ends of the continually-running rollers 12 14 and 26 24, as shown. The rollers 12, 13, and 14and the rollers 24, 25, and 26 are geared together, as shown, whereby they will be turned in unison and will act to continuously pay the web out of and into the press. From the driving-pinion 48, bynieans of the intermediate 500, the gear 53 is driven, and this gear 53 is fastened upon the end of the shaft 29, which is the shaft of the rotary looper G. The gear 53 also meshes with and drives a large intermediate 54, fastened on a stud or shaft 55, secured inthe main frame, as shown, and this intermediate 54 .meshes with and drives a large gear 56, mounted upon a shaft or stud 57, which is fastened to the frame l0, as shown. This gear 56 carries a crank-pin 58, on which is arranged a block 59, and this block 59 engages a slot 62 of the vertical portion 61 of the yoke 60, which yoke 60 is mounted so as to be capable of 'a reciprocating horizontal movement in the brackets 63 and 64, secured to the main framing, as shown. Thus as the gear 56 revolves the yoke will be given aforward-and-backward reciprocatiomwhich movement will be very smooth and powerful and will gradually reverse the parts evenly in both ways, as no pitmen are used. The yoke 60 has teeth' formed thereon, which engage the gear 66, fastened on the shaft 67, and, if desired, this shaft 67 may be carried across the press and journaled in the main frames 10 and 1,1. Fastened on this shaft 67 are two sectors 68, which mesh with teeth 44 of the carriages 42, before referred to, whereby as the yoke 60 is reciprocated the reciprocating motion will be multiplied and imparted to the carriages 42. This geared-up yoke maybe arranged in any desired manner and constitutes an efficient means for reciprocatingeither the single cylinder of a single machine or the double cylinders of a doublecylinder machine. The gear 56 is so arranged as to make half as many revolutions as the gear 53, and this is done in the present instance by making the gear 56 of double the size of the gear 53, whereby the rotary looper may act both to feed the web in and out of the press when-the cylinders are 0E impression inl either direction. A roll G9 may be arranged beneath the yoke 60 at the point at which the teethof the same engage the gear 66, and this roll may be mounted on a stud 70. This roll will act to keep the teeth before referred to. nicely in mesh.

The brakes 27 and 28, before referred to, may be lproperly operated by the following means: A cam 72 4may be arranged upon tlre ,shaft29, and bearing against the face of this cani` is arranged a rbller 73, which roller 73 is journaled in th'e end of a sliding airm 74. This arm 74 carries a block 75, and the roller is constantly pressed against the face of the cam by means of the spring 76, which bears against the block 75 yand at a fixed point or bracket 77. The rod 74 is mounted in suitable bearings, as shown, so as to be capable of a horizontal movement. The brake 27 is fas- `tened on a shaft 78, and the brake 28 is arranged on a similar shaft 80. On the ends of these shafts are arranged the arms 79 and 81, as shown, and these arms connect by li-nks 82 and 83 to the block 75, as shown. when the parts are in the position shown in Fig. 1 the spring 76 will press the block 75 to the left, and thus will cause the brakes to tightly engage the rollers 15 and 23 with a yielding pressure. design of the press is sc arranged as to move the block 75 slightly to the right from the position shown in Fig. 1, and thereby release or open. the brakes. These parts are so proportioned that the web will be tightly held The cam 72 in the'present roo by the brakes during the printing operation between the rollers 23 and 15,'which rollers are the points limiting the stationary part of the web, and the brakes will be released When ders and be fed during the reversal of the cylinders. rlhis braking mechanism forms an important device which can-be applied to any reciprocating cylinder printing press and is specially applicable to a reciprocatingcylinder printing-press in which the impression cylinder or cylinders print in both ways, as the strain in printing in both ways on the web comes in'both directions, and by use of the double brake a loop of the web, so 'to speak, as the web between the rollers 23 and 15, will be held stationary and taut during the printing operation.

The rollers 16 and 19, before referred to, are mounted in suitable brackets 800 and 810, secured to the main frames, as shown.

I wil-l now describe ing mechanism.l A

The entire feeding of the web around the impression-cylinders is preferably accomplished by a single piece, which I term a rotary looper,77 acting in conjunction with the continuously-running feeding-in and feeding-out rollers. This rotary looper Gis made cam-shaped and acts to take up and pay out the' action of the fcedany desired'construction, and one way is to makeI thesameof light @amr-shaped pulleys, as 301,'.a-ndto k-ey them upon the shaft 29, and thesepnl'leysmay be set as closely together as "desired, so as to form substantially a camsliapdfdrum. These pulleys are counter- -balan'd-bynieans of. lead or a solid hub, as

9d, jcast thewith, and by means of this coun- :terbalancin'githe `center of gravity of said rotaryrlvoper' fwill. be arranged to coincide with-:the axisofthe shaft 29, whereby the rotarylooper-cah Vrevolve very smoothly and at aghigh"Speedfwithout vibration or jar.

. Figs. ll. and' 3' the impression-cylinders areshown as in impression and as moving to the left.; but now to follow the action of the rotaryflooper refereuceshould be had to Figs. 4,15, and G. `In Fig. 4 the impression-cylin- 1 'ders areshown as just clearing the forms on theirlmovement, to the left and as commencjing their reversing movement at their lefthand extreme. ln Fig. 5 the cylinders are shown at their left-hand extreme, and in Fig. G the cylinders are shown as just engaging the-forms on their movement to the 'right and as' having completed their left-hand reversing movement. Suppose now that the impression-cylinders are so timed and designed that they will vhe upon and off the forms an equal time-that is, supposing foity-Iive-degree lines to be drawn through the center of the shaft 57. Then the portion of the revolution of the crank-pin 58 included in the upper space will represent the movement of the impression-cylinders when they are on the forms and moving toward the right,V and the lower space will represent their printing movement to the left. The right and left hand spaces will represent their reversals. In other words, the crank-pin must revolve through ninety degrees, or a quarter-turn, to take an impression and the same distance to reverse the cylinders. This proportion or design is not always followed, but is a convenient arrangement. Between Figs. 4 and l, therefore, the crank-pin will have made ninety-degree movement in the right-,hand space, into which the crank-pin movement is supposed to be divided, or the crank-pin will have turned ninety degrees, or a quarter-turn. As the shaft 29 is geared to turn twice as fast as the crank-pin, the rotary looper G will have turned one hundred and eighty degrees during this quarter-turn of the crank-pin. Supf posing now that the length of the sheet which it is desired to print, including the margins, dsc., is twenty-four inches, then the continually-running feeding-in and feeding-out rol- 1ers will be so'speeded that during each' movement of the impression-cylinders they will pay in and out twenty-four inches of web, or during each complete forward-and-backward movement of the impression-cylinders they will pay in and out `forty-eight inches of web, or the length of two sheets. Starting now with the parts as shown in Fig. 4, where the impression-cylinders have just finished their printing movement to the left and are starting on their reversing movement, and suppose the impression-cylinders to be moved to their left-hand extreme, as shown in Fig.`

5, and then back to just engage the forms, as in Fig. 6, or to make a reversal occupying a quarter-turn of the crank-pin 56, during this time, as before stated, the rotary looper G will make a half-turn'and `the loop in that portion of the web that is between the rollers 24 and 23 will be relieved, while at the same.

time the loop will be take'n up in that portion of the web between theV rollers 15" and 14. During this quarter-turn of the crank-pin 56 the continuously-running feeding-in rollers and feeding-out rollers will have paid in and paid out twelve inches of web; but as it is desired to shift twenty-four inches of web, or the length 'of a sheet, around the impressioncylinders the `rotary looper G must take twelve inches of web from the lower loop and draw the same amount through the press up into the upper loop, which .twelve inches of web, added to the twelve inches of web fed in and out by the feeding-in and feeding-out rollers, will make a total shift of twenty-four inches of web. Now as the impression-cylinders move to the right over the form-beds the rollers 12, 13, and 14 will act to pay twelve loo u inches of web out of the press and the rollinches of web into the press; but during the l time that the cylinders are-in impression and moving to the right the rotary looper G will turn from the position shown in Fig. 6 back to the position shown in Fig. 4, and the rotary looper G is so proportioned and designed that it will evenly pay the loop of the web between the rollers 15 and 14 out to the delivering-rollers and will act to increase the web in the loop between the rollers 24 and 23 to take up the web paid in by the feedingein rollers. 'Thus in this last movement of the rotary looper the same will not act or have any tendency to disturb the web between the rollers 15 and 23. The brakes, acting in connection wilh these rollers, help the action of the rotary looper, as they will preventany slight inequalities and imperfections in the cam-surface of the rotary looper from disturbing the stationary portion of the web. The rotary looper G during the right-hand reversal of the impression-cylinders 0E the formbeds will turn again from the position shown in Fig. 4 to the position shown in Fig. 6, and

IIO

, sired,'this rotary cam could be used simply to the wrap of the web,.and

.very advantageous in connection with this thustwenty-four inches of web will se shifted around the impression-cylinders when they are reversing in their right-hand estreme.

If the wrap of the web en the rotary-looper G should be neglected, the rotary looper would ligure out to be what is known as a heartshapcd cam-that is, a cam in which the diameters are all equal, but in which the radii angularly constantly increase and decrease for one hundred and eighty degrees; but in designing the cam account has to be taken of the cam or rotary looper is'so proportioned that the web during the printing action of the cylinders, as before described, will be evenly taken up in the lower loop and will be evenly paid out in the upper loop. Thus this rotary looper G forms a very neat, simple, and efficient device for feeding the web into and out of the press.

Another great advantage that follows from the use of therotary looper G is as follows: It will be seen by reference to the vdiagrammatic figures that the long point II ofv the rotary looper G always moves in the same direction as that in which the web is moving, or, in fact, it might be said that the whole surface of the rotary looper, where the same bears upon the web, moves in the same direction as that in which the web is moving. It will further be Seen that the surface of the rotary looper will move substantially at the same speed as the web nioves'inA the loops.l There may be a slip on the web due to the cam action, although this slip is very slight; but as the looper moves in the same direction as the web it will comb or coax the web forward, whereby when the brakes are released and the looper comes into action the web will be very quickly started and very easily pulled forward through the press. Therefore it is rotary looper to turn the same so that the same will rub or comb the web in a proper direction to feed the same through the press.

The rotary looper can be applied and used in connection with any device in which it is desired to intermittently move the web or its equivalent through a portion of a mechanism for any purpose. Tapes carrying sheets 'are of course the equivalent of a web. Again, this rotary looper G couldbe used by running the same practically at half the speed at which the same now runs relatively to the impression-cylinders to feed the web forward in a press `in which the cylinders only print in one direction-such, for example, as is shown in Letters Patent to WV. P. Kidder, No. 291,521, granted January 8, 1884.-. vThis rotary looper consists in its simplest form of means, as guides, for leading the material to' form aloop and a rotating member interposed in each loop.

In the figures previously described I have shown the rot-ary looper or cam as accomplishing the double function both of feeding the web into and out of the press; but, if defeed the web intothe press or out of the press, or a different looper and feed out, as shown in Figs. 7 and S. In Fig. 7 the impression-cylinders C and l.) are shown as commencing their reversing move ment at their left-hand extremes and in Fig. 8 are shown as having completed their reversing movement. In this case a rotary Alooper J, similar in construction tothe rotary looper G, before described, and having a long point II', is interposed in the loop formed between the rollers 1G and 14, and another rotary looper K is interposed in the loop of the web between the rollers 24 and 23, and this rotary looper K has a long point or end ll?. These rotary loopers are geared to turn in the same direction, and in Fig. 7 the long points of the same are shown as pointing down in the same direction, and in Fig. S theyI will also be pointing in the same direction, but upwardly instead of downwardly. This double rotary looper will act the saine as th-e rotary looper G, except that the looper J will act to feed the web out, and the rotary looper K will act to feed the web into the press. There are many other ways in which this rotary looper. could be proportioned and designed; and I do not at all wish to be limited to any specific construction herein shown and described so far as my broad invention is concerned. In this last modification the lower looper K could be omitted and dependence for the entire feed could be placed upon the upper looper J. With this arrangement the lower loop would be simply a loose loop in the web, from which the feed around the impression-cylinders would be pulled. In designing this cam-shaped looper of course the contour of the same would be varied if Vthe proportion of the movement of the imprescould be used to feed inv TOO sion-cylinders during the printing movement relatively to the reversing movement should be varied. Y

In the. offset-preventing device, as before described, any suitable Huid may be used, as oil, as is described in the Stonemetz application before referred to, or water could be used, and in this latter case the offset-preventing device would Work upon the principle of that claimed in my patent granted July l5, 1.890, No. 432,289.'

The details and arrangements of the various parts that I have shown and described may be varied and differenti y arranged by a skilled assi? mechanic without departingfrom the scope of my invention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
